Using plant nutrient landscapes to assess Anthropocene effects on insect herbivores

Global climate change will dramatically affect insect herbivores through changes in plant quality. Linking how multiple climate factors affect plant macronutrient content may be the most accurate way to understand the response of insect herbivores. Studies should embrace the complexity of interacting climate factors in natural systems and characterize shifts in multidimensional plant nutrient landscapes. This nutrient landscape simplifies interpretation of climate effects, although selection of appropriate currencies, scale, and interactions with allelochemicals present challenges. By assessing climate change through the filter of nutrient landscapes we could gain an understanding of how complex interacting climate change drivers affect the 'buffet' available to different insect herbivores.
